Notholirion is a small Asian genus of bulbous plants in the lily family, Liliaceae.

[2] It is closely related to Lilium, but each individual flowers only once, and then dies after producing offsets.

Leaves are basal, produced in autumn and winter.

[3][4] Baker (1874)[5] considered Notholirion to be a subgenus of Fritillaria, but Boissier (1884)[4] separated it as a distinct genus.

The evolutionary and phylogenetic relationships between the genera currently included in Liliaceae are shown in the following Cladogram: Tricyrtis Streptopus Prosartes Scoliopus Calochortus Clintonia Medeola Tulipa Amana Erythronium Gagea (Lloydia) Notholirion Cardiocrinum Lilium (Nomocharis) Fritillaria List of species:[6][7][3]
